[0013] Accordingly, the user can write or input data at any position on the touch panel. By the application software package, the data can be identified. The character written by the user can be stored in the storage apparatus. As the liquid crystal display panel has a dimension of 100 mm×140 mm to 190 mm×260 mm, which is much larger than that of the personal data assistant, it is easily for the user to write with. Therefore, the electronic note pad provided by the invention is writing friendly and has versatile functions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Referring to FIG. 1, an embodiment of an electronic note pad is shown. The user can write data or make a graph directly on the electronic note pad 10. The electronic note pad 10 comprises a liquid crystal display panel 102, a touch panel 104, a computer host 106, and a wrist slider 108. An application software package is stored in the computer host 106. A clear picture of the structure of the electronic note pad 10 can be obtained in FIG. 2. FIG. 2 shows the side views of wrist slide 108, touch panel 104, the liquid crystal display panel 102 and the computer host 106 from top to bottom. The following paragraphs will describe the functions for each of the elements.

[0020] The liquid crystal display panel 102 uses liquid crystals to display the manually written data or the drawn graph. The length by width of the liquid crystal display panel 102 is ranged from about 100 mm×140 mm to about 190 mm×260 mm. As this liquid crystal display area is much larger than that of the personal data assistant, it is easier for the user to write data.

[0021] The touch panel 104 is connected to the liquid crystal display panel 104. Various function options are displayed on the touch panel 104. By touching any of the function options, the specific function is selected and performed. Further, one can directly write data or draw a picture on the touch panel 104.

[0022] The wrist slider 108 is connected to the touch panel 104. The configuration of the wrist slider 108 is shown in FIG. 3. In FIG. 3, the wrist slider 108 can slide up and down, and be withdrawn or restored by a winding mechanism. The wrist slider 108 prevents the user from mistakenly touching the touch panel 104 during identification by the application software package.

[0023] The computer host 106 is connected to the liquid crystal display panel 102. FIG. 4 shows the functional diagram of the computer host 106. The computer host 106 comprises a microprocessor 402, a storage apparatus 404, a voice recording apparatus 406 and an infrared transmission apparatus 408. The microprocessor 402 processes the written or input data and the graph, and controls various functions of the electronic note pad 10. The storage apparatus 404 stores the data and the graph. In this embodiment, the storage apparatus 404 includes a memory card. The full memory card can always be conveniently replaced with a new empty one. The recording apparatus 406 records the voice of the user while inputting or writing data. Thereby, the content of the data is easier to understand. The infrared transmission apparatus 408 allows data transmission by infrared signal between the electronic note pad 10 and any computer.

[0024] The application software package is stored in the computer host 106 for data recognition or identification. The data is then stored in the computer host 106 and operated in the operating system thereof. When the user is writing data or making a graph, the data or graph is identified by the application software package and then stored in the memory card of the computer host 106. The data or graph is identified from the top to the bottom of the touch panel 104 by the application software package. Further, the input data stored in the memory card can be stored in the original form, or edited as required.

[0025] In addition, when the data or graph is input in the electronic note pad 10, the data or color of the graph can be changed to elicit the identification thereof. The electronic note pad 10 can also be used as an electronic dictionary or a tool for commencing various conversions.

[0026] According to the above, the user can write or input data at any position of the touch panel.
